[RFC PATCH 0/5] rcu: fix sparse warnings

[Pranith Kumar <bobby.prani@gmail.com>]

The following patch series fixes sparse warning. There are still 3 warnings left
which I am figuring out. I wanted to send these to get feedback and see if I am
on the right path.

Patch 1 is the significant one which involves some refactoring. I am guessing
the 3 remaining sparse warnings will require similar refactoring.

Patch 4 remove the __noreturn attribute as this confuses sparse. I am not sure
if removing this is the right thing to do or if we should be fixing sparse.

The other 3 are trivial.
